    Please see my code below, I have sorted out all my coding to work how I want it too, but for some reason I just can't get it to load the map when you open it up in a browser. Can anyone see where I have gone wrong and guide me to get it work please. Thank you.

    I've not revised all code but your map had not loaded because you use paths you've not defined so I comment them out. Also you are not calling initMap(). Here: polly = pollies[p] = new google.maps.Polygon(polly.latlng.lat, polly.latlng.lng); use polly latling you already have, no need for paths. no need for formatCodes function. Also give height and width of the div with id of map.

    I don't know why you need 2 initialization functions.

    I partially fixed the code. The map is loading.

    
<div id="map" style="width: 500px; height: 500px"></div>
